Pagination Patterns

Use first + skip for large result sets (The Graph returns up to 1000 entities per query).

query pairs($skip: Int!) {
  pairs(first: 1000, skip: $skip) {
    id
  }
}
query tokens($skip: Int!) {
  tokens(first: 1000, skip: $skip) {
    id
    name
    symbol
  }
}

Notes

  • Keep addresses lowercase in filters and IDs.
  • Use block-based queries for time-travel snapshots.
  • centurionFactory is the protocol-level aggregate entity for v2 subgraph metrics.
